RAM ATTACHMENT FOR WELL-DRILLING MACHINES.

Specification of Letters Patent.

Patented Dec. 17, 1918.

Application filed July 5, 1917. Serial No. 178,708,

7 '0 (ZZZ whom it may concern Be it known that I. HARRY E. Bnown, a

citizen of the United States, residing at ment to a weli drilling machine tooperate a rain for dressing drill similar work;

A further object of the invention is the provision of novel means for mounting-the ram for adjustment in various directions, and for reciprocating it.

With the foregoing and othenobjects in bits or doing other view'which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing wherein the device is shown in a Single elevation, portions being shown in section, and portions being broken away. V

The device embodies a tubular attaching member or case 1 having a radial apertured ear 2 extending therefrom between its ends to engage the wrist pin 3 which is adjustable in apertures 4 of the crank 5 which rotates with the band wheel 6 of the drilling machine, whereby the member 1 is given a crank motion of desired extent by properly adjusting the wrist pin on which the member 1 is mounted for turning movement.

The member 1 is provided therein between its ends with an apertured partition or shoulder 7 through which a spring rod 8 is slidable longitudinally of the member 1. Opposite alining tubular spring housings 9 and 10 have their adjacent ends threadedly or otherwise engaged within the ends of the member 1, and said rod 8 extends completely through said housings, coiled wire expansion springs 11 and 12 surrounding said rod within the respective housings 9 and 10 and being confined between the partition 7 and nuts 13 and l l threaded and adjustable upon the rod 8 and slidable within the respective housings 9 and 10. The housing 10 is rela tively long, and the nut l is located between the ends thereof, a removable sleeve 15 through which said rod is slidable, being threaded or otherwise engaged within the free end of the housing 10.

The relatively long tubular connecting rod 17 is employed for connecting the spring rod 8 and ram, the spring rod fitting telescopically, or slidably within the connecting rodl'l', and being held fast to the'connecb ing rod by means of a pin 18 inserted through said parts. Therod 8 is provided with a longitudinal series of apertures 19 for the reception of the pin 18, to adjust the rods relatively.

A knuckle=20 embodying pivotally con-- nected members 21 and 22 has the member 21 threadedly or otherwise connected to the free end of the connecting rod 17 opposite to the spring rod, while the member 22 is threadedly or otherwise connected to the butt end of the ram 24, whereby said ram is reciprocated with the rods during the rotation of the crank.

As a means for suspending the ram for vertical and angular adjustments, it is provided near its opposite ends with eyes 25 or other suitable attaching means, to which the ends of a suspended cable 26 are attached. Said cable passes over a double pulley block 27 hun from the derrick 28 of the machine, and the intermediate loop portion of the cable 26 passes around a drum or reel 29 mounted within a floating frame 30, and said drum is adapted to be rotated by a crank 31 or other suitable means.

The frame 30 has a cable 32 connected thereto and wound upon a drum 33 having a ratchet wheel 34 engaged by a pawl 35 to prevent the cable 32 unwinding, excepting when the pawl is removed from the ratchet wheel. The drum 33 is rotated by means of a crank 36 or other suitable operating member. By winding up and paying out the cable 32, this will lower the frame 30 and drum 29 and enable them to move upwardly, respectively, thereby moving both runs of the suspended cable 26 in one direction or the other, for raising or lowering the ram to the desired height. Said cable 26 provides a swinging hanger from which the ram is suspended for reciprocation, and the ram can be adjusted to various angular po sitions, by rotating the drum 29 to move the runs of the cable 26 in opposite directions, thereby raising one end of the ram while the other is lowered. It is thus possible to properly adjust the ram to operate on a drill bit or other object which is being dressed or otherwise worked.

Vith the member 1 attached to the crank 5, said crank when rotated will move the member 1 through a circular path, the partition 7 alternately compressing the springs 11 and 12, whereby to yieldably reciprocate the spring rod and connecting rod to which it is attached, and consequently operating the ram with a sharp efiective extra move ment. When it is desired to hold the ram at a certain angle relative to the connecting rod, a pin 23 or other suitable means can be used for locking the knuckle members 21 and 22 at a fixed angle relatively, which will accomplish the desired result.

Having thus described the invention, what is claimed as new is:

1. An attachment of the character. de- 1 scribed embodying a ram, means for reciprocating it, means connected to the ram for suspending it for reciprocation and open able for adjusting the ram angularly, and

suspending it for reciprocation, and means for operating the cable to raise and lower the ram and for operating the cable to adjust the ram angularly.

3. An attachment of the character described embodying a ram, means for reciprocating it, a cable having its ends connected to the ram near the ends thereof, a

floating device to which said cable is connected and operable for operating the cable to adjust the ram angularly while suspended by the cable, and means connected to said device for moving it to raise and lower the ram.

in testimony that I claim the foregoing as my own, I have hereto aiiixed my signature-in the presence of two witnesses.
